Document Summary
Electrical engineers design systems that have two main objectives: to gather, store, process and present information, to distribute, store and convert energy between various forms. Major classifications: communication systems generate, transmit and distribute information. Examples: telephone systems, radar systems, sattelite systems,. : computer systems process and store information in digital form. Examples: a typical modern automobile contains tens of special purpose computers. Many electronic devices, household appliances, chemical processes and railroad switching yards routinely controlled through computers: signal processing systems transform signals and the information contained in them into a the useful form. Examples: image processing, voice recognition, fault detection,: power systems generate, transmit and distribute electric power. Electric power is generate in large quantity in power plants by nuclear, hydroelectric and thermal (coal-, oil-, or gas fired) generators. Power is transmitted and distributed across the country by transmission lines and power grid: control systems gather information with sensors and use electrical energy to control a physical process.
